Scientifically proven technology that enables athletes to ride harder, longer and faster with less fatigue. By increasing the size of the gear when you push the hardest (downward stroke) and then decrease it to get through top and bottom dead zones quickly. the principle being the force on the pedal is constantly proportional to the muscular force of the rider.
The chain rings varying diameter alters the effective gear ratio though out the pedal stroke, producing a higher gear on the downstroke when the rider has more power and then reducing the gear on the upstroke. The ovalizatio factor is extreme, a 38 tooth ring equates to pushing a 42 tooth on the down stroke and a mere 36 tooth at the “dead spot” this translates to up to a 10% increase in power output which can result in put to a 3% increase in speed!
